This 18-inch barrel is manufactured from 4150 CMV steel and finished in a salt bath nitride treatment inside and out, ensuring durability, corrosion resistance, and extended barrel life. It features button rifling with a 1:10" twist rate, optimized for stabilizing a variety of .308 Win projectile weights, including heavier match and hunting bullets.
The pencil profile minimizes front-end weight while maintaining structural integrity and heat resistance. The barrel is threaded with a 5/8x24 pattern, making it compatible with most .30-caliber muzzle brakes, flash hiders, and suppressors. With an AR-10 compatible design and lightweight construction, this barrel is perfect for a fast-handling, long-range capable rifle.
